EXC_BAD_INSTRUCTION in cancel disk retrieve task.

[onevcat]

The problem still exists in Xcode 7 GM. So I guess I should opt-out the disk task canceling temporarily (since it is not a common scene to cancel a disk search at all).

@hankbao Thanks for reporting this. Yes, I believe it is the same issue.

Ref commit e271e3e

Once it gets fixed, we should add this back to Kingfisher.

Any luck with this after iOS 9 officially released?

[onevcat]

@hankbao With no luck. It is still crashing.

[hankbao]

Bad Apple.

Found a workaround according to an Apple engineer working on Swift compiler https://twitter.com/jckarter/status/641963107225501696

Thanks for the information.

Sure, we can get a workaround by wrapping it with Objective-C. But I am not quite willing to introduce it into Kingfisher, since it is a pure Swift implementation now. It is not a big problem with lacking of disk task cancel for this project, so I decided to opt it from Kingfisher temporarily.

[hankbao]

That's alright.

This is fixed in Xcode 7.1 beta 2. So we could add it back when the new Xcode gets released.

[hankbao]

👍

Now Xcode 7.1 was released. We could get it back and I will send a p-r on it later today.

[hankbao]

Finally ;)

Fixed in #128
